Abstract (en)
The method involves measuring parameters of cells (2a-2n) of a battery (1), and synchronously transmitting the parameters to a central monitoring unit (4) using pulse-width modulated signals. The signals are added in the monitoring unit, and steps in the added staircase-shaped signal are interpreted as measured values of the cells in the monitoring unit. The measured values are isolated from the added signal, and a deviation of the parameters of the cells from a reference value of the respective cell is derived as the measured values. An independent claim is also included for a cell monitoring unit comprising a measuring device.
Abstract (de)
Es wird ein Verfahren zur Überwachung eines Akkumulators (1) mit mehreren Zellen (2, 2a..2n) angegeben, bei dem ein Parameter einer Zelle (2, 2a..2n) gemessen und an eine zentrale Überwachungseinheit (4) übermittelt wird. Erfindungsgemäss erfolgt die Übermittlung des Messwerts mit Hilfe eines pulsweitenmodulierten Signals. Weiterhin werden eine erfindungsgemässe Zellüberwachungseinheit (3, 3a..3n), eine erfindungsgemässe zentrale Überwachungseinheit (4) sowie ein erfindungsgemässer Akkumulator (1) zur Durchführung des erfindungsgemässen Verfahrens angegeben.
